They must have snuck in a 94th county, because it ain't one of the 93 the rest of us are familiar with.
This is the only "sarper COunty" I can find referenced on google:
(other than this phony news story)
"...Logan County Arkansas-
Originally called Sarper County when formed in 1871, Logan County was renamed in 1875 in honor of early pioneer James Logan..."
Must mean Sarpy.
